Product specifications
The CS4271 is a highly integrated audio codec that utilizes a single-ended input and differential output architecture to deliver high analog performance and to maximize system flexibility with an on-chip oscillator, output volume control with soft ramp and zero crossing, selectable digital filter response, and integrated level shifters for direct interface to logic levels from 2.5 V to 5 V. The on-chip oscillator eliminates the need for an external crystal oscillator circuit, thereby reducing overall design cost and conserving circuit board space. The CS4271 automatically uses the on-chip oscillator in the absence of an applied main clock, simplifying system design.
